Take the micro USB cable and plug it into the bottom of the vape mod. The Elf Twist battery needs approx. an hour and a half to two hours to fully charge.
How to Twist adjust the voltage in Elf vape pen.
On the side of the Elf mode, just above the twist knob, you will see a little red arrow. This is your current voltage settings indicator. You can twist it left and right and you will see that the voltage runs from 2.5 all the way up to 4.0 volts. Simply spin this twist knob and line up your desired voltage with a little red arrow. 4.0V is the maximum setting, the most intense and powerful one and 2.5V is the smallest and essentially the least intense temperature or voltage setting.
